Objective To observe the effect of mirror therapy and sensory reeducation on sensory function recovery after thumb recon-struction with second toe transplantation. Methods Forty patients after thumb reconstruction with second toe transplantation from January, 2011 to January, 2014 were divided into control group (n=20) and training group (n=20). Both groups accepted routine nursing and rehabili-tation, while the training group accepted mirror therapy and sensory reeducation training in addition. They were followed up for six to eigh-teen months after operation (average 9.3 months) with the two-point discrimination (2-PD) of transplanted toe pulp. Results 2-PD was (7.15±1.15) mm in the training group, very shorter than (10.23±2.23) mm of the control group (t=5.4898, P<0.001). Conclusion The mirror therapy combined with sensory reeducation training can improve the sensory function of the finger pulp that transplanted from the second toe.

Objective To analyze the causes of peripherally inserted central catheter (PICC) relat-ed infections, study the types of pathogens and their drug sensitivities in order to supply evidence for clini-cal medication. Methods 110 cancer patients were analyzed for PICC related infections and blood sam-pies underwent bacterial culture. Results Of 110 cases of cancer patients, catheter-related infections were found in 11 patients (10.00%), including 9 cases of local infection (8.18%), and 2 cases of hemato-ge-nous infection (1.82%). Catheter-related infections were not associated with gender, age, types of catheter, venous selection, and the inserted length of intravenous catheter. Catheter- related infections were likely to be associated with the indwelling time of catheters. Conclusions To avoid the infections related to long-term PICC, strict aseptic operation and standardized maintaining procedures are required.

Objective To explore the efficacy and safety of terminating biochemical pregnancy (the stage in which intrauterine or ectopic pregnancy cannot be confirmed) with mifepristone and misoprostol. Methods Mifepristone (150 mg) combined with misoprostol (600 ?g) 3 days later were given to 500 biochemical pregnancies (G_1),500 early clinical pregnancies (G_2) and 500 clinical pregnancies (G_3) which were classified according to amenorrhea days,serum human chorionic gonadotropin-beta subunit (?- hCG) and vaginal B-ultrasonic examinations.All were observed for 6 hours after taking misoprostol and returned for assessment per week.Results Expulsion of conceptus was G_1 123 (24.6%,123/500),G_2 438 (87.6%,438/500) and G_3 467 (93.4%,467/500).Failure rate was G_1 6 (1.2%,6/500),G_2 24 (4.8%,24/500) and G_3 79 (15.8%,79/500) for ongoing pregnancies,hospitalizations for suspected ectopic pregnancies and surgical intervention for heavy or long-time bleeding.Bleeding cases during the administration of mifepristone were G_1 272 (54.4%,272/500),G_2 141 (28.2%,141/500) and G_3 87 (17.4%,87/500);the mean bleeding days were G_1 (5.8?1.5),G_2 (9.0?2.9) and G_3 (14.3?5.9) days.Other side effects including abdominal pain,nausea,vomiting and diarrhea were low and light in each group,increasing with advancing gestational age.Menses recovery was 486 (97.2%,486/500),452 (90.4%,452/500) and 433 (86.6%,433/500) for each group on scheduled time.Satisfaction was 499 (99.8%,499/500),485 (97.0%,485/500) and 369 (73.8%,369/500) respectively.Conclusion Mifepristone and misoprostol in combination is as safe,and effective for termination of biochemical pregnancies as ordinary medical abortion.It does not need to wait till ectopie pregnancy is excluded.

Professor LI Zhi-dao, according to acupoint selection of syndrome differentiation in TCM basic theory, concluded a new therapy, namely "tonifying three qi" that is mainly based on three acupoints in the Conception Vessel. This method is consisted of Danzhong (CV 17), Zhongwan (CV 12) and Qihai (CV 6) in the Conception Vessel, which could successively nourish clear qi, stomach qi and original qi. In clinic, according to the severity of symptoms of three qi, the acupoints are selected flexibly, which could respectively treat deficiency of heart-lung qi, deficiency of stomach-spleen qi and deficiency of original qi. Some examples are also given in the article.

To observe the effects of Danshen-containing serum on SuFu and DYRK2 expression in the HSCs stimulated by leptin. SD rats (n = 60) were used to make danshen-containing serum by gastric perfusion for ten days with Danshen water decoction, normal saline and colchicine. The HSCs that were cultured in vitro would be stimulated for 24 hours by leptin (100 μg x L(-1)) except blank control group, after being intervened, the drug serum in each group would be cultured at 37 degrees C in 5% incubator. The cells would be collected after 24 hours, then the effects of danshen-containing serum on the proliferation of HSCs were detected by MTT, the expression of SuFu mRNA and DYRK2 mRNA were detected by RT-PCR, the expression of SuFu and DYRK2 proteins were tested by Western blot. Compared with blank control group, the expression of DYRK2 mRNA and DYRK2 proteins were enhanced obviously after stimulated the HSCs of rats by leptin (P < 0.01), but the expression of SuFu mRNA and SuFu proteins were decreased significantly (P < 0.01). Compared with the model group, after cyclopamine group (Hh pathway inhibitor), Danshen-containing serum and colchicine were interfered, the expression of DYRK2 mRNA and DYRK2 proteins were decreased clearly (P < 0.01), but the expression of SuFu mRNA and SuFu proteins were increased significantly (P < 0.01 or P < 0.05). Compared with model group, adding purmorphamine (Hh pathway agonist) to model group and making it activate could increase the expression of DYRK2 mRNA and DYRK2 proteins, but the expression of SuFu mRNA and SuFu proteins were decreased significantly (P < 0.01). Compared with the model group, using the Danshen-containing serum to interfere the purmorphamine group could make the expression of DYRK2 mRNA and DYRK2 proteins decrease and the expression of SuFu mRNA and SuFu proteins increase significantly (P < 0.01). Danshen-containing serum would inhibition the activation and increment of HSCs by interfering the expression of SuFu and DYRK2 which were induced by leptin.

Objective To measure the financial burden incurred by hypertension to urban patients in Beijing, Nanjing and Hangzhou cities. Methods Two communities were sampled from the three cities randomly, and 300 hypertension patients were sampled randomly from hypertension control files in each community for questionnaire survey. Results Health expenditure of the families with hypertension patients accounts for 14. 4% of the family's income, and 18. 2% of the family's expenditure, a ratio far beyond the national average (10.6 %). However, the majority of them report the burden as affordable.The basic medical insurance for urban residents helps alleviate the financial burden of hypertension patients and the extent of such burden has a close bearing on the outcome of hypertension treatment and prevention. Conclusion Effective community-based blood-pressure monitoring and control system is key to reducing the financial burden of hypertension. The reimbursement policy for hypertensive patients within the basic medical insurance is expected to be further improved.

Objective To study the clinical value of transcervical resection under hysteroscope in treatment of placental remnants.Methods From March 2003 to April 2006,14 cases of placental remnants were treated with transcervical resection under hysteroscope.They included 3 cases of term birth,and 11 cases of midtrimester induction of labor.Drug pretreatment was performed for those who had more than 80 U/L of blood beta-human chorionic gonadotropin (?-hCG) level,including mifepristone (RU486), Chinese herbs and methotrexate(MTX).RU486 was taken orally at 25 mg,three times daily and misoprostol was given 600 ?g at one dose on the third day.MTX was given by deep intramuscular injection at 1 mg/m~2 if ?-hCG was higher than 150 U/L.Bipolar evaporation was used in the operation with alternation of resection and forceps holder under ultrasonographic supervision.After operation a circular contraceptive device was placed followed by hormone periodic treatment such as estradiol valerate for 2-4 months.Results Under the monitoring by ultrasonography,14 operations were all performed smoothly.The follow-up was from 6 months to 2 years.Menstruations in almost all the cases were recovered,and 3 cases of those were pregnant and delivered smoothly 4,6 and 7 months after operation.Conclusion The transcervical resection under hysteroscope is useful in treatment of placental remnants with obvious effects,little trauma and few complications.

Objective To assess left ventricular (LV) global systolic function in patients with essential hypertension with normal geometric LV by 3-dimensional ultrasound speckle tracking imaging(3D-STI). Methods Fifty patients with essential hypertension were enrolled in this study, 29 normal subjects matched with age and sex were selected as control groups. LV global longitudinal peak systolic strain (GLS), radial peak systolic strain (GRS), circumferential peak systolic strain (GCS), LV global 3-dimentional radial peak systolic strain (3DGRS) were measured in all subjects by 3D-STI from the apical full-volume image and compared between groups. LV ejection fraction (LVEF) was acquired from 3D-STI.Results Compared with controls, LV GLS, GRS, GCS and 3DGRS were significantly reduced in patients with hypertension ( P ＜ 0.05 for all). A Pearson correlate revealed that LV GCS, GLS and GRS corresponded with LVEF( r1 =0.930, P1 ＜0.001; r2 = 0.705, P2 ＜0.001; r3 =0.474, P3 =0.001,respectively) in patients with hypertension, and LV GCS, GLS correlated with LVEF( r1 = 0. 838, P1 ＜0. 001; r2 = 0. 697, P2 ＜ 0. 001, respectively) in normal subjects. Conclusions LV global 3D strain decreases in patients with hypertension in the early period,3D-STI could evaluate the early change of heart function in patients with hypertension. LV circumferential movement plays a major role in the LV 3D movement and impacts on LVEF.
